Description: Dominance type, canopy cover, and tree size maps were developed for Prince of Wales Island. Over 2,600 Square Miles (including other federal, state, native, and private land inholdings) were mapped through a partnership between the Geospatial Technology and Applications Center (GTAC), Tongass National Forest, Alaska Regional Office, and State of Alaska. The Tongass National Forest and their partners prepared the regional classification system, identified the desired map units (map classes) and provided general project management. GTAC provided project support and expertise in vegetation mapping. A combination of ground and helicopter reference data was used to inform the classification models that output the final maps. Federal and State field personnel collected plot data on the ground.
Classification models were used to characterize modeling units (mapping polygons) with the following vegetation attributes: 1) dominance type; 2) tree canopy cover; 3) tree size; and 4) tall shrub canopy cover. The minimum map feature depicted on the map is 0.25 acres. All map products were designed according to the Forest Service mid-level vegetation mapping standards in order to be stored in the Forest GIS and National databases. This map product was generated using imagery primarily acquired in 2018 & 2019. The field data used as reference information for this mapping project was collected in the summer of 2018. Therefore, the final map can be considered indicative of the existing vegetation conditions found on Prince of Wales Island in 2018.
